The so-called craftsmanship of metal precision stamping parts is the difficulty of processing this metal precision stamping part. Perfect stamping craftsmanship should ensure high raw material utilization, few processing steps, simple structure of stamping dies and long service life, high quality of stamping parts, simple and convenient operation of stamping workers. There are many factors that affect the craftsmanship of metal precision stamping parts, such as product shape, size, precision and performance.

1. The shape of the metal precision stamping parts should be simple and symmetrical, preferably composed of arcs and straight lines, so that less waste can be generated when planning the layout.

2. Try to avoid long cantilevers or slots on the metal precision stamping parts, and the minimum width should be greater than twice the thickness of the material. The distance between the holes and the holes, holes and edges of the stamping parts should not be too small.

3. The size of the punching should not be too small to avoid breaking the punching needle during the stamping process.

4. Under normal circumstances, the shape of the stamping parts should not have sharp corners, but should use rounded corners to transition, which is conducive to the processing of the stamping die and increases the service life of the die.

5. When punching punches on punching and bending parts and punching deep drawing parts, the distance from the edge of the hole to the straight wall of the workpiece should not be too small. If the distance is too small, the hole will be deformed after punching. If punched later, the punching needle will also be easily broken.
